Abstract: PURPOSE:To enable clasp fastening positions to be selected finely and arbitrarily, and prevent thin band pieces from being cut off by releasing the clasp inserting sides of a plurality of the thin band pieces extended in the vertical direction, at the clasp fastening sections, to arrange the inserting sides so that counter side edges may be put together in order with the adjacent thin band pieces, and by fitting them at fixed intervals. CONSTITUTION:A plurality of thin band pieces 3 extended in the vertical direction are released on the inserting sides 3A of clasps 2, and are arranged so that edges 3B on the counter sides may be put together in order with the adjacent thin band pieces 3, and they are fitted with sewing threads 4 or the like at fixed intervals for enabling the clasps 2 to be inserted into. When the clasps 2 are fastened, then according to the dimension and thickness of the leg of a user, the arbitrary thin band pieces 3 are selected, and are inserted in the direction of an arrow head A from the released sides 3A and are fitted on each other. In this case, the clasps 2 are inserted into the internal sides of the thin band pieces 3 put together, and can be stably fastened. Besides, the thin band pieces 3 are fitted so that the pieces 3 adjacent to each other may be partially put together, and so they are not caught in contact with them in the direction of an arrow head B, and flexibility is kept, and a physical disorder is not found when the clasps 2 are fastened.

Title: Mig welding method
Inventor: TAKAGI SEIJI
IPC: B23K9/29
Filed: 1988-02-05
Abstract: PURPOSE:To prevent minute fusion of an Al wire with a chip on the chip and prevent the occurrence of buckling of the wire by using a tube with good feed performance and little wire feed resistance and a tube with good conductivity respectively for a curved part and other parts of a welding torch. CONSTITUTION:The inner tube 7B such as Teflon with little wire feed resistance is used for a bend for MIG or a part thereof. As a result, chips of the Al wire are reduced and Al wire buckling due to clogging of a wire path is extremely reduced. In addition, since the inner tube 7A of a pipe or a coil with good conductivity is used for an almost straight line part and a part with a limited curve, electricity is supplied smoothly to the Al wire. Accordingly, an arc is not generated between the wire and the chip 1 and the minute fusion of the wire with the chip 1 is prevented and the wire buckling is not caused.
